"To have your story pulled, you feel like you've won the lottery," he says.

The family's appearance on Monday's episode of Dr. Philincluded Alex's parents and his sister. The appearance brought them face-to-face for the first time with Ralph Looseman, the man the Teehees believe killed 20-year-old Alex four-and-a-half years ago.

"We believe in our hearts he's guilty," Tab says.

Ralph Looseman defended himself on the Dr. Phil Show saying, "I was accused everything from beating Alex with a blunt object, to running him over with my car, to throwing him out of my vehicle. I'm totally innocent of everything they are accusing me of."

The Teehee family says they don't believe Looseman.

"We believe he's not being a hundred percent truthful. It's difficult to sit there and listen to him," says Tab.

In July 2008, Tab says his son met up with Looseman and two other men in Port Charlotte for some free ecstasy. A witness heard the men argue and saw a car take off.

"They struck him with a car and left them there to die," Tab argues.

An hour earlier, one of the men in the car left Alex threatening messages on his cell phone.

"They left two threatening messages. No lack of words. They said they were going to kill him."

Alex's father says his son never heard the messages. If he had, he would have never met up with the men.

In 2010, the Charlotte County State Attorney's Office set Looseman free two days before going to trial for vehicular homicide manslaughter and dropped the case.

The Teehees say one of the men in the car has relatives who work for the Charlotte County Sheriff's Office.

"It's been a long drawn out failure of the justice system," Tab says.

The Teehee family says four-and-a-half years after Alex's death they are still determined to have their day in court.

Tab wears a T-shirt with a family picture that reads, "The dead cannot cry out for justice, it's the duty of the living to do so for them."

"It is a fight for justice," says Teehee. "Alex left behind two little boys a lot of what we do is for them." Alex's sons are 6 and 7 years old.

The Teehees hope state legislators will take notice of their son's case. They also hope their appearance on the Dr. Phil Show will bring forth new information in the case.
